Beit known vthat I, ABRAHAM FINN, a. citizen of Russia, residing atElizabeth, yin the county of Union and State ot" New Jersey, haveinvented new andfusetul ImprovementsrinPlastering Devices, of which thefollowing l,is aspecication. p y

This invention relates to in'iprovements in plastering devices.

The principal object Vof 'the1 inventioniis the provision of a deviceiorusein plastering the ceilingand walls of a room by applying the plasterin sections, by iirst placing the plaster upon the device and thenlifting the same. to thespot where the plaster is to be secured. .Ifdesiredthe device may be constructed of :a-Y size large enough to permitthe entire ysurface vto be plastered in a minimum number of operations..f

,Another object of the invention is tol provide a devicewhich maybeoperated by a single person and which eliminates the objectionofapplying the plaster to the. ceiling of` a room by theruse o'l' a trowelor other implement which is a lvery tiresome process.

A further? object is to provide a plastering device whichis simple inconstruction, cheap ot manufacture and-easy of operation.

Vith these and other objects in view, the

Vinvention resides in certain novel construction and combination and`arrangement of parts, the essential features of which are hereinafterullydescribed, areparticularb7 pointed out in the appended claims, andare illustratedin the accompanying drawings in which 4 f Figure 1 is aperspective view of my improved plastering device of the type forapplying the finishing coat otl plaster.

Figure 2 is a top planview of the same. ,Figure 3 is a sectional view onthe, line SW3 of Figure 2. Figure .4 is an enlarged detail sectionalview on vthe line 4 4 of. Figure 2.

Figure 5 is an enlarged detail sectional view on the line 5-5 of Figure2.

l Figure 6 is a diagrammatic view showing the manner in'which theplaster is: applied. Figure 7 is a modiiied form showing the type ofdevice used for applying the rough coat of plaster.r

Figure 8 is a sectional view on the line 8-8 of Figure 7. y

Referring` more particularly to the drawings, the reference character Adesignates lsides ot the ears.

my invention in its entirety, and which in" cludes a board or platform10, to the underside ci which is securedhandles 11 at opposite endsthereof. The handles 11 are ,of

such construction as to serve as legs for sup y porting' the device whenthe same is resting' upon the ground or other support. The platform 10inthe present instance is shown as square in plan, but may be of anysuitable shape such as triangular, and completell. encircling the edgesof the platform is a movable wall 12. The wall ,12 includes two highsides 12a and two lower sides 12band is yieldingly supported. at thecorners yby a means 13, and which means includes adepending bracket'ist' provided withaseat i5 for receiving the one end oi" a spring 16.The wail 12 rests upon the other end of thel springs to hold thewall ina raised position abovethe side edges ot the plat-form to prevent theplaster which is placed thereon from spreadingover the side edges.Depending rom opposite sides of the walls are handles 17 which arepivotally, connected to the wall a d which are arranged adjacent thehandles 11 of the platform. From the description, thus vfar, lit will beseen that the handles 11 and 17 may be lsiinultaneeusly graspedbythehands, and the handle 17 depressed so as to move thewall'l.)J.downward Jelow the surface of the platform against the tension of thesprings 16, and uponrelease of the handle 17 the wall will move back toits normal position. y

As hereinbe'tore mentioned, the plaster is applied in sections as showndiagrammatically in Figure (i, and when so applying the same, it hasbeen found necessary to provide a. guide means, 1S 'for co-action withthe structure which receives the plaster, for holding` the device in asteady position so that the section may he applied evenly to thesections already applied, and for gauging the thickness of the plasterwhen applying the same. The means 1 8 comprises an angular rail 19 whichsurrounds twosides ot the platform and is spaced from the wall 12 vasclearly shown in Figure 2. The rail 19 is adiustably supported withrelation to the platform by a bracket 2O secured to certain oi thebrackets 1li and which bravi-:ets have spaced ears 21 provided withslots 22 opening on opposite Extending through the Slot-S 22 O @21011.bracketis ascrew Q3, having a knurled head 21 at one end and a head 25at its other end said last head being formed with a slot or lierf 2G inthe top face thereof. The rail 19 rests in the slots of the respectivescrews and is removaby held therein by setscrews 27. A lock nut 28 isthreaded to each screw between the space-d ears and coacts with thelower ear for holding the same in adjusted position after the desiredadjustment of the rail is obtained by rotating the knurled head 24. Byforming slots in the recesses of the brackets, it is possible to removethe screw should it be desired to collapse the structure.

Mounted adjacent one corner of the platform is an adjusting' member 29,which is threaded in the platform and is provided with a manipulatinghead 30. The member is adjusted to the level of the guide rail andco-acts with the same for evenly applying the plaster.

It will be understood that in practice, plaster is spread upon theplatform 10, and the device lifted to the desired spot by grasping thehandles 11, after which the handles 17 are depressed and pressureapplied to the device until the rail 19 is flat against the structurewhich receives the plaster. The plasterwill then adhere to the previouscoat, as it will be understood that the device shown in Figures 1 to 5in.

elusive is employed for applying the finishing coat, after which thedevice is lowered and the operation repeated.

One of the side walls is provided with cut-away portions 31 to permitthe excess plaster to flow from the platform when applying the same, anda trough 32 encircles the walls to receive the overflow. The lower sides12b of the walls are provided with pins 33 for aligning the section tobe applied with the portion of the ceiling already covered.

In order to prevent the plaster from sticking to the platform, I providea strip of W ater proof material 34 which is first placed upon theplatform prior to filling the same with plaster, and the same is held inposition thereon by pins 35. The strip of material will leave theplatform when the plaster is applied, but may be removed from theceiling after the same is thoroughly dried.

In the form shown in Figures 7 and 8 for applying the first coat ofplaster or for plastering walls which necessitates the tilting of thedevice, I provide the platform with spring fingers 36 which projectslightly above the upper surface of the platform to prevent the plasterfrom slipping from the' platform during the application of the same. Inother words, the fingers serve to reinforce the congealed mass. Thewalls 12 in this form are of the same height and the pins 33 aredispensed with. It is unnecessary to use the strip 34 in the device asthel strip is only necessary to give the plaster a finished appearancelVhile I have described what I deem to be the most desirable embodimentof my invention, it is obvious that many of the details may be variedwithout in any way departing from the spirit of my invention, and Itherefore do not limitmyself to the exact details of construction hereinset forth nor to anything less than the whole of my invention limitedonly by the appended claims.
